serial_crusher:So, I can just ignore all signs in that neighborhood, since I don't know which ones are real and which aren't? I'll get right on that.

This is actually closer to the truth than you think.

People (usually "for the children!" Types) think that stop signs are magical devices that cause drivers to obey speed limits and drive safely. The problem is that when stop signs are installed in places where they aren't warranted, people tend to ignore them, and the reduced impact of the signs carries over to other signs, even ones that are warranted.

People try to use stop signs to make drivers slow down, but unless the stop sign meets strict engineering criteria, it actually results in even worse driver behavior (rolling through stops, speeding between stop signs out f frustration, ignoring well-placed stop signs, etc...)

TL;DR - stop signs have a very specific purpose, and when used for other purposes tend to actually make a bad situation worse.

Well, since you get to put up your own signs as you see fit, I guess they won't mind if I slap up a few of my own.

Of course, the speed limit is too low, so a few 70mph signs should do the trick to improve traffic flow. Hey, people got to get to where they are going... right? Maybe a few "douchebag" crossing signs too... I'm still working on the design for that one.
